Woom 4
The Woom 4 is a lightweight kids bike purpose-built for ages 6-8, with easy-reach brake levers and proportions scaled to a child's body.
A Real Bike, Scaled for Kids The Woom 4 isn't a shrunken adult bike -- every component, from brake lever reach to crank length, is scaled specifically for young riders, making it dramatically lighter and easier to control than typical big-box kids bikes. Key Features Ultralight aluminum frame, often half the weight of comparable kids bikes Kid-specific brake levers sized for small hands Puncture-resistant tires for worry-free neighborhood riding Not sure about sizing?

Frequently Asked Questions
- What height or age is the Woom 4 suitable for?
- Wheel size is a better guide than age for the Woom 4 — the most important measurement is your child's inside leg length and standover height, not a birthday. Bring your child into The Cycle Zone and we'll size them properly against the Woom 4 and similar models so you get a bike that fits now rather than one they'll grow into eventually.
- Will the Woom 4 last as my child grows, or will we need to size up soon?
- Like most kids' bikes, the Woom 4 has a reasonable amount of adjustment in the saddle height and, on most models, the handlebar reach, which buys a bit of extra time before a full size change is needed. That said, kids' bikes are generally sized for a specific height range rather than "grown into," so expect to move up a size within a year or two of steady growth.
- Does the Woom 4 come with a warranty?
- Yes, the Woom 4 is covered by Woom's standard frame and component warranty against manufacturing defects. The Cycle Zone also carries out a full pre-delivery inspection and build on every kids' bike we sell, so it arrives properly assembled and safety-checked, and we're on hand to help with any warranty queries afterwards.
